I’m sometimes asked what custom function settings I select on my Canon EOS 1D Mark IV camera, so I figured I’d share this information so that you can compare my settings with your own. I have also made my custom settings file available below for you to apply to your own camera if you want to try this. First, here are my settings.

Looking at Hands

Save Your Settings and Try Mine

If you want to try my settings the easy way, Save your own settings first, then download my settings file below, and apply that.

To save your settings:

• Go to the Custom Functions menu and select [C.Fn settings register/apply]
• Turn the Quick Control Dial and select [Register], then select [Set]
• Turn the Quick Control Dial and select a Set from Sets 1, 2 or 3, to save your settings to, then press the Set button on your camera
• Select [OK]

You might also want to save your setting to a memory card. I do this anyway, and make a local copy on my hard drive. I also copy these to my SD card, as I don’t format that as often as my CF cards.

To save your settings to a memory card:

• Select [Save/load settings on media] from the third Set-up Menu (yellow wrench/spanner) and press the Set button on your camera
• Select [Save]
• I usually select [Change file name] and enter a name for that camera and/or settings set (1, 2 or 3).

Once you have your own settings backed up, download my settings file and copy it to a memory card, and put that into your camera.

Note that this is a compressed zip file that will expand to a file called MBP1DMIV.CSD.

To Load settings:

• Select [Save/load settings on media] from the third Set-up Menu and press the Set button on your camera
• Select [Load] and select the file MBP1DMIV.CSD from your memory card

You will only be able to restore this file to another Canon EOS 1D Mark IV.

Remember, this will change how your camera operates unless you have yours set up exactly the same as mine. You can easily change back to your own settings if you do what I said above, but if you are not comfortable with any of this, don’t do it.

Other Useful Settings:

Here are a few other settings like I ensure I use, but that are not custom functions and are not included in the settings file above.

• Histogram = RGB. I always use the RGB histogram. It is so much more useful than the standard brightness histogram, although you can now see both when cycling through the information screens with the Info button
• Color Space = Adobe RGB. This has no real bearing on my workflow, as I use RAW with Lightroom/ACR, but I like to leave this on
• Live View Settings:
  • Grid Display = Grid 1. The 9 rectangle grid, for rule of thirds reference in Live View
  • Expo. Simulation = Enable. This is now on by default, but I ensure it stays on. I use Live View a lot!

Additional Information:

I arrived at my current settings based on thorough reading of the 1D Mark IV’s User Manual and the following documents from Canon, as well as a lot of tweaking based on trial and error during shooting.

Canon Document: AI Servo AF Custom Function & ISO Speed Settings Guide
Canon Document: Canon EOS 1D Mark IV White Paper : The Next Chapter of EOS, A New Standard of Excellence

I hope this information is of some help!
